Here's the set of graphics I made from which I created my own handcrafted piecepack sets. I've decided to offer these to the piecepack community to use freely.
They are released with a Creative Commons Attribution License 3.0 ( http://creativecommons.org/licenses/by/3.0/ ) so they can be freely used and distributed.
This file includes the graphics (divided into regular suits and season suits) plus a few games I've created for the system myself. Those are released with their own licenses. I've also included a version of the graphics with no background for those that wish to use their own, or just want it white as the original graphics were.
The background I used for the wood-like set is called Anigre ( http://www.cadyou.com/downloads/view/1084 ) and was created by madhav ( http://www.cadyou.com/users/view/madhav ) who released it under a Creative Commons Attribution License 3.0 ( http://creativecommons.org/licenses/by/3.0/ )
